FRITZ ALTMANN, OF BERLIN, GERMANY.

APPLIANCE FOR BURNING HYDROCARBON OlLS WITH BLUE 0R BUNSEN FLAME.

SPECIFICATION forming part of Letters Patent No. 598,262, dated February1, 1898. Application filed November 13, 1896. $erial No. 611,975. (Nomodel.)

T0 otZZ whom, it may. concern:

Be it known that I, FRITZ ALTMANN, a citizen of Germany, residing atBerlin, in the Kingdom of Prussia and Empire of Germany, have inventedcertain new and useful Improvements in Appliances for BurningHydrocarbdn Oils with Blue or Bunsen Flame, of which the following is aspecification.

This invention relates to an improved means for burning hydrocarbon oilswith a blue or Bunsen flame.

The object of this invention is to accomplish the burning of petroleumand other hydrocarbon oils with a blue flame by mixing a certainpercentage of steam with the hydrocarbon vapor and conducting themixture to the burner at which the flame is produced. By theintroduction of the steam a considerable quantity of oxygen is suppliedto the flame, so that a perfect combustion of the carbon in the sametakes place. The result is a non-smoking hot blue flame, such as isrequired for incandescent lights. This blue flame is also useful onaccount of the properties referred to for cooking, heating, soldering,and other a'pplicationsin the arts.

In the accompanying drawings two different forms of appliances are shownwhich can be used for carrying out my invention, in

rounded by an exterior body or shell 2', which is made in the nature ofa lamp-fount and which is supported on a suitable stand A. One of thechambers a and b is intended for receiving petroleum or other liquidhydrocarbon oil, while the other is intended for receiving Water. Thechambers a and b are provided at the bottom with small extensionchambersc, which connect with the chambers a b by small openings, the supply ofliqui-ds therethrough being controlled by means of conical valves m. Thelower ends of the extension -chambers c are connected with tubes (1,which are located near asmall heating-lamp g, so that by the heat of thesame the liquids in the tubes (1 C1 are vaporized.

The hydrocarbon vapors and the steam generated are then conducted bysmall tubes e e, which connect with the upper ends of the tubes (1, intoa tubular mixing-retort f, the lower end of which is located above theheating-flame of the lamp g, While to the upper end the burner h isapplied. The hydrocarbon vapors are mixed with the steam in the retort fand retained at a high temperature by the heating-flame, so that theheated mixture is conducted to the burner when it is required for use.

The supply of hydrocarbon oil and water to the small chambers c isregulated by the valves m, which are provided with valvestems k, thatextend through the bottom openings in the chamberso and b into aguidesleeve 7t" at the top of the same and through the topsupply-openings of said chambers, the upper ends being acted upon by thescrewcaps Z, by which the supply-openings in the .body 1; and thechambers a and b are closed.

The valve-stems 7c are of such length that when the screw-caps areclosed the valves m are pressed down sufficiently, so that they areopened and the supply of liquids into the chamber 0 takes place. Whenthe screw-caps Zare unscrewed forthe purpose of refilling the chambers aand b, the valves m are automatically closed by the action of helicalsprings 0, which are interposed between the bottoms of the chambers aand b and collars p on the valve-stems k. The valves m are opened whenthe screw-caps Z are closed again by pressing the valve-stems 7c indownward direction against'the' tension of the springs 0.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An appliance for burning liquid hydrocarbons with ablue flame, which consists of two separate chambers,one being anoil-chamber and the other a water-chamber, placed in close proximity andconstructed to provide a central space between them, a retort located insaid space and communicating with said chambers, a burner located aboveand communicating with the retort, and a subburner arranged under theretort for heating it, substantially as set forth.

2. An appliance for burning liquid hydrocarbons with a blue flame, whichconsists of two separate chambers, one being an oil-chan1- ber and theother a water-chamber, said chambers being placed in proximity andconstructed to provide a central space between them, tubes extendingfrom the lower portions of saidchambers up into the space between them,a retort arranged in said space, additional tubes connected With theupper ends of the aforesaid tubes and extending down into the saidretort, a burner located above and connected with the retort,=and asubburner arranged under the retort for heating
